Turning graphene into light nanosensors

Turning graphene into light nanosensors Graphene has many properties, but it does not absorb light very well. To remedy this, physicists resort to embedding a sheet of graphene in a flat photonic crystal. Scientists now demonstrate that by altering the temperature in such a hybrid cavity structure, they can tune its capacity for optical absorption. This means graphene-based nano-devices could potentially be used as temperature-sensitive sensors. https://ift.tt/eA8V8J
